A Keizer husband and wife who were longtime volunteers for the Marion County Sheriff's Office were ordered held on $1 million bail each by a Marion County Circuit judge Friday on sex-abuse accusations.

Casey Wenger, 33, and his wife, Rosa Linda Wenger, 31, made their first appearance in court Friday. Casey Wenger is accused of 21 counts of encouraging child sex abuse, according to court records, although the jail also lists an accusation of second-degree sex abuse. Rosa Linda Wenger is accused of one count of third-degree sex abuse and 20 counts of encouraging child sex abuse.

An arraignment was scheduled for April 4.

The couple is accused of having an inappropriate sexual relationship with a 17-year-old volunteer in the search-and-rescue program they helped lead, according to a press release from the Marion County Sheriff's Office. The sheriff's office, which received the complaint on Monday, asked Keizer Police to investigate the claims.

Casey Wenger became a volunteer for the sheriff's office in 1994 when he joined the "Team 18" search-and-rescue program, according to sheriff's spokesman Sgt. Chris Baldridge. Rosa Linda Wenger became a volunteer in 2003. The couple were crew leaders for the team, which mainly includes volunteers under age 18 who assist with some search-and-rescue functions for the sheriff's office.

The Wengers trained volunteers and deployed them when needed for helping ground searches for missing people and other functions, Baldridge wrote in a press release.

"Individuals' personal actions like this undermine the public's trust and confidence placed in our office," Sheriff Jason Myers said in a statement. "The moment this was reported, we took action to ensure that the individuals would be held responsible and that those within the Team 18 program would be safe. Our goal now is to focus on the members of Team 18 who are obviously just as shocked and upset as we are."
